SD4SP Project

Stratospheric Dynamics for Seasonal Prediction

Project Overview

The SD4SP Project focuses on the mechanisms of stratosphere-troposphere coupling. Particularly the impacts of El Niño – Southern Oscillation (ENSO) and the Quasi-Biennial Oscillation (QBO) over the North Atlantic – European (NAE) region through their teleconnection via the stratosphere. The aim of SD4SP is to identify these mechanisms to improve their representation in climate models.

Conceptual model of the coupling between the polar vortex and tropospheric circulation.
